# Simple Machines - Levers, Mechanical Advantage, Pulleys, Wheel And Axle, Inclined Planes, Screws, Compound Machines - Wedges

### kinds six wheels special

A simple machine is a device for doing work that has only one part. Most authorities list six kinds of simple machines: levers, pulleys, wheels and axles, inclined planes, wedges, and screws. One can argue, however, that these six machines are not entirely different from each other. Pulleys and wheels and axles, for example, are really special kinds of levers, and wedges and screws are special kinds of inclined planes.

A wedge is an inclined plane that can be moved. Chisels, knives, hatches, carpenter's planes, and axes are all examples of a wedge. Wedges can have only one sloping plane, as in a carpenter's plane, or they can have two, as in a knife blade. The mechanical advantage of the wedge is calculated in the same way as with an inclined plane by dividing the length of the wedge by its width at the thickest edge.

it does not say much about levers, how many are there what are more examples of levers?

Mechanical Advantage is not a simple machine! It is a measure of how much a force-multiplier machine helps us do work!

Can you put al list of compound machines also i'm confused

I need to know more about possibilities of new machines made from these simple machines. Technically speaking, can you please put up examples of machines that have a leaver, wedge, etc?

That would be of a great help to me.

Thank you

Your excellent web page contains an error. The mechanical advantage of a wedge is not calculated in the same way for an inclined plane. To calculate the M.A. of a wedge, you divide length by thickness. For an inclined plane, it's slope by thickness.

yelo this was really and is helpful. if it didnt help you then im sorry but you dont have to say that. if there is something mean to say dont say it........................................please .....................thank you ....bye!!!!!!!!!!!

Is it possible for the mechanical advantages of two compound machines with different-sized inclined planes to be the same? Explain why or why not. If you know the answer, please kindly email me: cshelly12345@gmail.com
